Just tried to have a ride but as Zwift just updated and it’s now bumped me off and unable to log in! just keeps telling me that “invalid password or user name!” I’ve restarted everything clear my cache! I can log into my account with no problem but can’t use the game at all! any ides or just an upgrade bug! Even the email that it’s send never arrives to reset it!
@William_Worswick , I’m having the same issue. 
Did you ever get yours to work?
Yes got it up and running! When it upgraded it manage to loose a letter from the email address so wouldn’t let me log in!
